cmd/go: fixes
* Install tools into tool dir always
(Fixes issue 3049. Fixes issue 2868. Fixes issue 2925.)
* Make packages depend on compiler, linker (Fixes issue 3036.)
* Do not recompile packages across roots (Fixes issue 3149.)
* Allow use of binary-only packages (Fixes issue 2775.)
* Avoid duplicate cgo dependencies (Fixes issue 3001.)
* Show less in go get -x. (Fixes issue 2926.)
* Do not force repo root for existing checkout (Fixes issue 2969.)
* Show full syntax error list always (Fixes issue 2811.)
* Clean arguments before processing (Fixes issue 3034.)
* Add flags for compiler, linker arguments (Fixes issue 2996.)
* Pass flags in make.bash (Fixes issue 3091.)
* Unify build flags, defined in one place.
* Clean up error messages (Fixes issue 3075. Fixes issue 2923.)
* Support local import paths (Fixes issue 3118.)
* Allow top-level package outside $GOPATH (Fixes issue 3009.)
In addition to these fixes, all commands now take a list of
go files as a way to specify a single package, just as go build and
go run always have. This means you can:
go list -json x.go
go fix x.go
go vet x.go
go test x_test.go
Preliminary tests in test.bash.
Mainly testing things that the ordinary build does not.
I don't mind if the script doesn't run on Windows.
I expect that gccgo support is now broken, and I hope that
people will feel free to file issues and/or send CLs to fix it. :-)
